It’s an early scene in the 2005 Johnny Cash biopic, Walk the Line. The young Cash, played by Joaquin Phoenix, is auditioning for the man who might make him the next Elvis Presley. That man was Sam Phillips, the Sun Records impresario from Memphis.

The fictional Cash walks into the room and begins playing a Gospel song. The fictional Phillips is not impressed, and tells the fictional Cash that no one listens to Gospel anymore, and that he should play something more meaningful. More relevant.

Cash did. The rest was history.

Well, not quite. It turns out that Cash, who was born on February 26, 1932, didn’t stop playing Gospel music at all. Nearly a quarter of the songs he wrote were in some way about his faith or the Bible, and many others were influenced by his Christian worldview.

But there wasn’t a single Gospel song on the Walk the Line soundtrack. Somehow, the screenwriters left out that important dimension of his musical catalogue. And there wasn’t a single mention of the greatest love of Cash’s life: Jesus Christ. That’s a love story the screenwriters of Walk the Line just couldn’t wrap their minds around.
